Over the past ten years, the Technical University of Denmark has made an effort to collect and dissiminate research within chemical engineering thermodynamics to industrial collaborators through CAPE-OPEN [1]. Ensuring a successful knowledge transfer from university to industry is an iterative task that requires commitment from all partners as well as a good communication across disciplines. The development of CAPE-OPEN compliant scientific software is a multidisciplinary task that requires insight in software development and process simulation as well as an in-depth knowledge of the underlying research. Furthermore, as a project matures and the solution becomes more widely adopted and used in the industry, it becomes important to ensure the quality of the software and results produced from process simulation. A new software solution (ThermoSystem 4.0) has been built from the combined experiences and research from the CHIGP project [2]. ThermoSystem is a solution for performing calculations with state of the art thermodynamic models, including PC-SAFT and CPA. Version 4 consists of a new CAPE-OPEN 1.0 and 1.1 compatible C# library [3] and a robust core thermodynamic library (built in FORTRAN) [4].

We present how the new version solves a range of issues related to research, implementation and optimization, and those related to the state of the current implementation of the CAPE-OPEN standard in commercial process simulators. We show results from process simulation of larger flow sheets and present an overview of the future developments in the CHIGP project.
